摘　　要：[目的]对土牛膝进行生药学鉴定。[方法]采用显微鉴别、薄层色谱鉴别和高效液相色谱法对土牛膝进行定性和定量鉴定。[结果]土牛膝的性状特征和组织构造特征明显;并且,测得土牛膝中齐墩果酸的平均含量为0.445 3%,蜕皮甾酮的平均含量为0.103 3%。[结论]该方法对土牛膝的生药学性状进行了鉴定,其结果可为土牛膝质量标准的制定提供参考依据。[ Objective ] To identify the roots of Achyranthes aspera L.. [ Method ] A qualitative and quantitative study on the roots of Achyranthes aspera L. was carried out through microscopic identification, TLC and HPLC. [ Result ] Obvious characteristics were found in the tissue structures of Achyranthes aspera L.. In addition, the average content of oleanolic acid and ecdysterone was 0. 445 3% and 0. 103 3%, respectively. [ Conclusion] The result can be taken as the reference basis for the establishment of quality standards for Achyranthes aspera L..
